Research on the Green Evaluation System of Manufacturing Process

In view of the current domestic most of the problems of “three highs” iron and steel enterprise, to comprehensive multi-level evaluation of iron and steel enterprise, contribution rate of the resources and the environment, this paper proposes a process for manufacturing iron and steel enterprise based on gray correlation analysis method of the green evaluation method, to systematically study the greening level of iron and steel enterprise. First, according to the manufacturing process of iron and steel enterprises, a multi-level green evaluation index system is established, and then the actual production data in the enterprise is processed using the gray correlation analysis method to obtain the optimal values and build a matrix. According to the gray system theory, the gray correlation coefficient matrix is calculated, and finally according to the size of the correlation, green sex compared to the enterprise. In this paper, an example is applied to make an empirical study on this method. The results show that this method is effective and can provide an objective scientific basis for the green evaluation of iron and steel enterprises.
